Quad movie posters are 30″×40″, versus one-sheet movie posters, which are 27″×40″ (or 27″×41″ for older ones). Quad is the standard size in the UK.
This UK quad (Style B) poster was issued for the release of Barbarella in 1968.
The main heading with the title of the film is typeset in one of the phototype versions of Edelgotisch by either PLINC or Lettergraphics.
Interestingly, it appears to be a heavier weight than Edelgotisch as shown in Schelter & Giesecke specimens, and it is not condensed like the bold version that was later added and eventually renamed Othello.
Without samples of PLINC or Lettergraphics versions of Edelgotisch to reference, it's unclear which version we see here. There’s no record of either PLINC or Lettergraphics adding additional weights to their versions of Edelgotisch.
When the title is written again below the main heading, it’s in the normal style from the early specimens.
While the questions in the speech bubbles are lettering, the credits at the bottom are set in a range of sans serifs, including Alternate Gothic and possibly News Gothic Extra Condensed and Monotype Grotesque or similar.
